Embodiment Construction
[0044] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0045] figure 1 A schematic diagram showing a method for inverting the resistivity of a shale gas reservoir according to an embodiment of the present invention. Such as figure 1 As shown, the method includes:
[0046] S1: Obtain the apparent resistivity of the target area by using a wide-area electromagnetic method;
[0047] S2: collecting seismic data in the target area;
[0048] S3: Constraint inversion is performed on the apparent resistivity according to the seismic data to obtain the distribution variation law of the resistivity of the shale gas reservoir in the target area.
[0049] The method for inverting the resistivity of shale gas reservoirs in this embodiment adopts the method of delineating shale gas reservoirs in multiple dimensions, which avoids the multi-solutions caused by inversion by seismic or electromagnetic single methods in the...
